HINGE FOR DOOR CONSTRUCTION Filed May 13, 1940 4 Sheets-Sheet 4 Patented Oct. 27, 1942 HINGE FOR DOOR CONSTRUCTION Henry J. Siess, Detroit, Mich, assignor to Crawford Door Company, Detroit, Mich, a corporation of Michigan Application May 18, 1940,8erial No.334,-72l

(Cl. Iii-171) sures of the sectional type and more specifically relates to hinge devices having separable mating parts which can be mounted on the door panels or sections at the factory and interlocked on the job to provide an articulated door.

The invention will hereinafter be specifically described in connection with an upward acting garage door of the sectional type, but it should be understood that the invention is not limited to such use, and, in general, is adapted for connecting pairs of movable members in articulate relation.

Heretofore, sectional type garage doors had the sections thereof hinged together by means of permanently united hinge parts. This required a mounting of the hinges on the job, since shipment of a full size articulate door was impractical. As a result, the door sections were assembled one by one from the bottom panel up, in the doorway, and the hinges were mounted on the thus positioned panels as the door sections were being built up. The mounting of the hinges on the vertical panels was a time-consuming and difiicult operation.

The present invention now deals with hook type hinges having separable mating parts connecting the door sections in articulate relation. The hinge parts can be disengaged and mounted individually, at the factory, in operative position;

on each door section or panel. The panels can' be shipped in individual relation with the hinge hardware thereon.

The hinges each have a pair of interlocking parts with one of the parts carrying a pin accom-- modating a roller which is engageable in tracks to guide the door sections. The door sections with the hinge parts thereon can bemounted successively in position in the doorway as is customary, but the sections are immediately interlocked into a single articulated door by the previ-' ous'ly mounted hinges thereon. This avoids the heretofore necessary time-consuming and dimcult operation of mounting the hinge hardware on the door sections as the same are being built up in the doorway.

The rollers carried by the hinges of this invention can be engaged in the vertical door tracks and the tracks, with the rollers mounted therein,

are then merely secured in position in the doorlocking hinge parts adapted to be individually mounted on the door sections and then readily interlocked for holding the door sections in articulate relation.

A further object of the invention is to vprovide an upward acting door construction of the sectional type including disengageable interlocking hinge parts holding the door-sections in articulated relation and atthe same time forming supports for guide rollers.

Another object of the invention is to provide hinges for. connecting door sections in articulate relation while at the same time providing axes .of rotation for guide rollers.

Another object of the invention is to' provide interr'itting adjoining edges for closure sections which are shaped to hold the sections in a single plane throughout their widths while at the same time accommodating articulate movementsioi the sections.

A further and specific object of the invention is to provide hinges for closure members which are readily locked. together during all normal articulate movements of the sections but which are also readily detachable from each. other without the aid of tools.

Another specific object of the invention is to provide hook type hinges for the side edges of sectional type doors which are locked in assembled relation in all normal operating positions of the door but which can be readily disengaged when the door sections are articulated through a greater angle than any operating angle.

A further specific object of the invention is to provide hook type hinges for sectional type doors which are locked together through a, sleeve carrying a guide roller. Other and further objects of the invention will be apparent from the following detailed description of the annexed sheets of drawings which disclose preferred embodiments of the invention.

As shown on the drawings:

In Figure 1 the reference numeral ID designates generally a doorway of a building or garage defined by side door jambs such as H, a lintel edge of the door sections.

I2 and a floor or sill [3. The doorway I9 is closed by a sectional type door I i composed of door sections Ma, Mb, Mo and hid connected together for articulate movement and. mounted on rollers l5 engageable in tracks such as IS. The tracks IS extend vertically along the inside of the doorway from the sill to the lintel and then curve inwardly into the building to horizontal portions suspended from the ceiling or side walls of the building (not shown). The door I 4 is thus mounted for vertical movement into and out of the doorway and for horizontal movement in an overhead position. The door in its fully opened position is disposed substantially horizontally along the horizontal track sections, and in its closed position is disposed vertically along the vertical track sections.

A spring-urged winding drum or sheave i1 is rotatably mounted on the lintel 12 of the doorway inside of the building by means of brackets such as Ila bolted to the lintel. A cable 18 extends from the sheave I! along the outer face of the door l4 and is secured at la in the bottom door section Ma. The spring-urged sheave I1 serves to wind up the cable l8 for counterbalancing the weight of the door to facilitate movement thereof from vertical closed position to horizontal overhead position. An unwinding of the cable from the sheave permits the door to close while at the same time movement of the door into a closed position winds up the spring to resist the gravity action of the weight of the door and to prepare the spring for the next opening operation.

As shown in Figures 2, 4 and 5, alternate door sections such as Mb have their side edges equipped with metal hinge parts such as 20. These hinge parts 20 include an angle plate having one leg 2| thereof extending over the inner broad face ,of the door sections and bolted to the door sections by means of bolts 22. The other leg 23 of the angle plate extends over the side This leg has an off- 1 set apertured portion 24 in spaced relation from the side edge of the door and extending beyond the bottom edge of the door sections. The offset portion 24 has a circular recess 25 therein communicating through the bottom edge thereof by a vertical slot 28.

The other alternate door sections such as Ma and l ic carry the male hinge part 21 composed of an angle plate having one leg 28 thereof extending over the inner broad face of the door sections and bolted to the sections by means of bolts 29. The other leg 30 of the plate extends over the side edge of the door sections as shown and has a free end portion 3| slightly offset from the door edge as shown in Figure 4 and extending beyond the top of the door sections. This free end 3| hasa pin 32 extending therethrough with the head 32a of the pin disposed between the door sections Ma and Mb and the inner face of the offset portion 3i. The pin 32 is fixedly mounted in the offset portion and projects laterally from the side edge of the door section. As shown in Figures 4 and 5, the axis of the pin 32 is about in line with the adjoining ends of the door sections.

The pin 32 is adapted to fit through the slot 25 in the female hinge member 29 so that the door section Mb can be assembled on the door I section Ma.

The roller I5 is mounted on a sleeve 33 adapted to fit overthe pin 32 and rotate therearound with the roller. The outside diameter of the sleeve 33 is larger than the slot 26 in the female member so that the assembly of the sleeve on the pin within the circular recess 25 locks'the male and female hinge parts together in articulate relation.

The door l4 can thus be built up from the sections Ma. and hid right in the doorway IE) by merely mounting the bottom door section I ia with its male hinge part thereon in position in the doorway against the door jambs H. succeeding sections are then built up on top of the section M by merely slipping the female hinge part over the pins of the male hinge part and by inserting the roller sleeve 33 over the pin to lock the hinge parts together. The rollers [5 are seated in the tracks l5 and the tracks are secured in position in the doorway. The assembly of the door is complete without previous assembly of the door sections out of the doorway or without necessity for mounting the door hinges on the sections in the doorway.

As shown in Figure 6, adjoining door sections such as Ma and 'l lb have their adjacent ends rabbeted for interfitting relation. Thus the door section 14a has a rounded head portion 34 projecting upwardly therefrom between the broad faces thereof. The rounded bead portion 34 terminates in an abutment surface 35 parallel with the inner broad face of the section but spaced inwardly from this broad face. The other end of the bead terminates in a fiat shoulder 36 normal to the outer broad face of the door. The inner face of the door section Ma is beveled as at 31 so that the abutment surface 35 has an inclined cut-out portion or bevel 31 therebeneath. The

abutment surface 35 is offset from the shoulder 35.

The adjoining door section I4b has a rounded recess 38 receiving the bead 34. The recess 38 is bounded by a finger 39 having an abutment surface 40 contacting the surface 35 when the door sections are in a single plane. The other side of the recess terminates in a finger 4| having an end 42 adapted to seat on the shoulder 35. than the curvature of the bead 34 so that the bead is not in full contact 'with the recessed surface. The bottom of the finger 39 is above the bottom of the finger 4i and is beveled upwardly as at 43.

inner broad faces thereof while the outer broad faces are flush. The door sections are adapted for articulate movement since the finger 4|.can

ride over the bead 34 while the bevel-ed surface .7

43 can move toward the beveled surface 31. Contact between the recess 38 and the bead 34 will be progressive as illustrated in dotted lines.

The fingers 39 and 4| together with their abutting surfaces hold the door sections along their entire lengths to prevent buckling thereof and when the door sections are in a single plane, a sealed effect is obtained without the aid of weatherstrips.

The bead 34' is not intended as a hinge part but is merely provided to fit into the recess 38 for holding the door sections in alignment along their entire lengths. The metal hinge parts described above take the load and the wood parts are not subjected to wearing action.

In Figures 7, 8, 9 and 10 the door sections [4a and Nib are equipped with a modified form of interlocking hinge part according to this invention. In these figures parts substantially identical with parts described in connection with The The recess 38 is at a different curvature Thus when the door sections are in a single plane a notch is formed along the of the door.

Figures 1 to 6 have been marked with the same 45. The recess 45 has a slot 45 extending therefrom through theinner edge of the free end portion 44. The slot 46 is of less width than the diameter of the recess 45. The slot 45 differs from the slot 26 illustrated in Figures 2 to 4 in that it extends through the inner edge of the female hinge portion instead of through the bottom edge.

The male hinge portion 47 on the door section [4a is composed of an angle plate having one leg 48 thereof extending over the inner face of the door section and bolted thereto by means of bolts 49 while the other leg 59 thereof extends over the side edge of the section. As shown in Figure 10, the legs 68 and 50 are preferably connected through a rounded portion 5| to prevent a right angle bend between the parts and thus increase the strength of the plate.

The leg 50 has a free end portion 553a carrying a pin 52 which projects therethrough and extends laterally from the side edges of the door section about in line with the mating ends thereof. The pin 52 is cylindrical for a major portion of its length but has a portion 5-3 of reduced size adapted to fit through the slot 46 of the female member. This reduced portion is inclined to the broad faces of the door section Ma as illustrated in Figure '7 at an angle such that the slot 46 of the female portion 48 can never be aligned therewith when seated in the recess 45 during normal articulated movements of the door sections in operative position.

However, as-illustrated in dotted lines in Figure '7, the female hinge part is adapted to be slipped over the reduced portion 53 of the male pin when the door section I4!) is at a greater angle than that reached by normal operation of the door. Then when the door sections are mounted'in operative position, the hinge parts are permanently locked. Each pin 52 can carry .a roller i 5 engag-eable in the tracks I6.

As illustrated in Figure 8, the door can be built up from the sections thereof in the doorway by mounting the sections step by step to bring their hinge parts into interlocking relation. The movement of the door sections from vertical to horizontal position is such that the same never reach an angle as great as that illustrated in Figure '7 for assembling the sections together.

In Figures 11 to 14 there is illustrated a still further modified interlocking hinge for the door sections Ma and Mb. In these figures, the reference numeral 50 designates generally the female hinge part composed of an angle plate having a leg 6| bolted to the inner broad face of the door section Illb by means of bolts 52 and a second leg '63 disposed over the side edge of the door section Mb. The leg 53 has a free end hook portion 54 projecting therefrom and beyond the end of the door section Mb. As shown in Figure 12, this hook portion 54 is slightly offset from the leg 63 so as to be in spaced relation from the door section.

The male hinge part '65 is mounted on the door section Ma and carrying a pin I extending laterally from the door section. A flange II is turned outwardly from the end portion 68 as shown.

As illustrated in Figure 11, the hook 64 of the fem-ale hinge section 60 is adapted to be slipped over the pin I0 of the male section '65 when the door sections Ma and I 6b are disposed in an angular relationship greater than that assumed during the normal operation of the door. The hook M, however, will engage the flange II on all normal articulated movements of the door sections and this flange will hold the hook on the pin to maintain the hinge parts in interlocking relation.

The door can be built up in position from the door sections in the same manner illustrated and described hereinabove;

The pin I0 receives a roller such as I thereover to guide the door sections in the tracks.

Another embodiment of the invention is illustrated in Figures 15, 16 and 17. In these figures the door sections Ma and Mb carry the male and female hinge parts in reverse relationship. In other words the door section Mb carries the male hinge part which is slipped into the female hinge part when the sections are substantially at right angles but which is held in the female part during all normal angular movements of the door sections in operation. The female hinge part has a hook member adapted to receive the pin only when the parts are at least in right-angular relationship and retaining the pin in all other angles greater than right angle relationship.

In Figures 15 to 17 the door section Ma carries the female hinge part 80 composed of an angle plate having one leg 8| thereof bolted to the inner face of the door section by means of bolts 82 and the other leg 83 thereof extending over the side edge of the door and having a free end portion 84 extending beyond the end of the door section. This free end portion 84 has a recess 85 therein opening toward the inner face of the door section along a downwardly inclined path. As illustrated in Figure 17, the free end portion 84 is offset from the side edges of the door sections Ma and Mb. The door section Mb carries the male hinge part 88 composed of an angle plate having one leg 8'! thereof extending over the inner face of the section and bolted thereto by means of bolts 83 while the other leg 89 thereof extends over the side edge of the door.

The leg 89 has a free end portion 90 adapted to fit between the end portion 84 of the female section and the side edges of the door sections as illustrated in Figure 17. The free end portion 90 is offset slightly from the edges of the door sections to accommodate the head 9| a of a pin 9| extending therethrough. The pin 9| projects laterally from the side edges of the door and is adapted to receive the sleeve 33 of the roller I5 in rotatable relation therearound.

The pin 00 is inserted in the recess 85 of the female hinge part 80 only when the door sections are in the angular relationship shown in Figure 15. When the door sections are mounted in operative position in a doorway, the same never assume an angular relationship greater than that shown in dotted'lines in Figure 16 so that 'the pin 9| cannot be removed from the recess because the recess opens downwardly and requires a greater angular relationship between the door sections to permit removal of the pin.

In the further modification shown in Figures 18 and 19, the door section Mb carries a female hinge part-I00 composed of an angle plate having a leg IOI bolted to the inner face of the door by means of bolts I02 and a second leg I03 extending over the side edge of the door. The leg I03 has a free end section I04 terminating short of the bottom end of the door section and turned outwardly and inwardly, as best shown in Figure 19, to provide a segmental annular recess I05.

The door section 14a carries the male hinge part I06 composed of an angle plate having one leg I0'I thereof extending over the inner face of the door section and bolted to the section by means of bolts I08 and a second leg portion I09 extending over the side edge of the door section. The leg I09 is provided with a slightly offset free end portion H0 extending beyond the top end of the door section Ma and carrying a laterally projecting pin III. As shown in Figure 19, the pin extends through the free end portion I I0 and has a head portion II Ia disposed between the door sections and the free end portion.

The top end of the free end portion I I0 has a segmental annular flange II2 adapted to be seated in the recess I05 of the female member for holding the door sections together in articulate relation.

The flange I I2 is adapted to be guided into the recess I05 by disposing the door section Mb in right-angular relationship with the section Ma. The flange IIZ can slide in the recess I05 to permit articulate movements of the door sections and will not be removed from the recess during normal operating movements of the door sections since, as shown in Figure 18, in dotted lines, the door section Mb does not assume an angular relationship relative to the door section Ma that is great enough to permit removal of the flange. However, the hinge parts are readily connected and the sectional door can be built up in the doorway from the door sections in the manner illustrated in Figure 8.

The pin III is adapted to receive the roller I5 and sleeve 33 thereon in the same manner illustrated in Figure 1'7.

From the above descriptions it should be understood that this invention now provides for the building up of articulated sectional type doors in place in a doorway through the medium of interlocking hinges containing male and female parts which are readily assembled and which, when assembled, will not permit separation of the door sections during any angular movements thereof occurring in operation of the door. The hinges provided by this invention carry pins which support rollers for guiding the sectional type door into and out of position in the doorway. The pins and rollers extend laterally from the side edges of the door sections.

The hinge parts of this invention are securely united to the door sections and have flanges overlapping the inner face of the sections so that securing means can enter transversely into the door sections thus affording a stronger connection than is possible by merely screwing hinge plates onto the side edges of the door.

It will, of course, be understood that various details of construction may be varied through a wide range without departing from the principles of this invention and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
